Notes : 1. In leaving water control: the heating will be activated as required by the water temperature
2. Leaving water control is not allowed when multi set point control according pattern B is used.
Note : When power returns after a power supply failure, the auto restart function reapplies the remote
controller settings at the time of the power supply failure. It is therefore recommended to leave
the auto restart function enabled. Note that with the function disabled the schedule timer will not
be activated when power returns to the unit after a power supply failure. Press the pr button to
enable the schedule timer again.

[8-00] Remote controller temperature control - leaving water control
When using the remote control delivered with the unit, 2 types of temperature control are
possible. Default [8-00] = 1 which means that the remote controller is used as room
thermostat, so the remote controller can be placed in the living room to control the room
temperature. Set [8-00] to 0 to use the unit in leaving water temperature control.
set point. The set point can be set manually, through the schedule timer or weather
dependent (automatic). The temperature range is between 25°C and 80°C and can be set by
ébi and ébj buttons.
[8-01] Auto restart
When a power failure occurred and the power returns to the unit, the system will
automatically restore it's settings and restart. This is the default setting [8-01] = 1. To disable
this auto restart function, set [8-01] to 0.
[8-03] Quiet mode
The unit has a quiet mode functionality for which 3 levels can be selected:
[8-03] = 1 low noise level 1 (default)
[8-03] = 2 low noise level 2
[8-03] = 3 low noise level 3
Activating this quiet mode is done by pushing the QUIET MODE button on the remote
controller or through the schedule timer.
[8-04] Freeze-up prevention
The unit has a freeze-up prevention functionality for which 3 levels can be selected:
[8-04] = 0 prevention level 0 (default: no prevention)
[8-04] = 1 prevention level 1
[8-04] = 2 prevention level 2
The freeze-up prevention is only active when the unit is in thermo OFF condition. If
prevention level 1 is enabled, the freeze-up prevention will start if the outdoor ambient
temperature <4°C and if leaving or return water temperature <7°C. For prevention level 2,
the freeze-up prevention will start as soon as the ambient temperature <4°C.
For both cases the pump will operate and if leaving or return water <5°C for 5 minutes the
unit will start up to prevent too low temperatures.
It is advised to enable freeze-up prevention if the indoor unit is located in a colder ambient
room (e.g. garage, ...) to prevent water freeze-up.
